o of Essex and State of New Jersey have in vented certain new and useful Improveme ts 1n Roller-Bearings to Resist Side and itnd c ltrain, fully described and represented in the following specification and the eeconipenying drawings, forming at part of [the some. I

This invention relates to roller-bearings in which cylindrical. rolls are employed to resist lateral strain, and the object of the invention is iJQPfOYltlG such cylindrical rolls also with means to-sustain endthrnst with but it very small amount of frictions resist ance. This object is secured by forming the hub and easing of the bearing respectively at their opposite ends with beveled hinges projected. slightly from the hub and easing beyond the line oi the roll-sects thereon, and providing one end of each roll with a. beveled collar fitted to one of the said beveled flanges and providing the other end of each roli with a loose ring haw ing a beveled shoulder fitted against the opposite beveled flange. Each roll is thus pro .YlLlE (l with means for contacting its opposite ends with flanges upon the hub and cos-- ing res tivelyt and the 'ollowing means are pl'()-u'r ,{l to reduce ."iction as much as possible where the ends of the roll engage with the flanges, and to prevent any 'illC- tionol resistance tron ii r the roll out of parallelism '1 0 client these r hub is projected sf toe roll-sent, :nn :1 gm we :uijzi line of died with roll the ni'edc it little ler Foil to rotate in Si tends pin ly line of the rol. eroted by such lmlzmco one :1? i arind tl tendency to tv-Jist inc roll nut oi position.

upon the and the toi et 3-. loose washer or hells may be interposed between the ring. and the zidjacent end of the roll to diminish the friction betweensuch parts. Each roll is proportioned so that collar and ring just lit between the beveled flanges of the hub and casing and hue prevent eny end movement of the easin one direction. l i here thrust is to be isted in both directions, two such beer v are applied to the some shaft or journel, and disposed in reverse positions so that the resist thrust in either direction.

The invention will be nnderstoodhy reference to thennnexed drawing, in whitin- Fignre l is a. longitudinal section of a wheel-center with a journal-therein, the upper left-hand roll being shown in section at the center of the roll. with balls fitted be i. hind the ring it; the upper right-hand roll being shown partly in section with the cage behind it, and a 'W'ash'erZ upon the stud i, the lower right-hand roll being shown in section on line in Fig. 2, and the lower lefohnnd roll being shoi'v'n in section on line g yin Fig. 2. Fig. 2 a cross-section on line :2 2 in Fi 3.; Fig. 3 is a side View of the hub on the iei't-lnind end of the journal; Fig. i an elevation of the hub in the righthzind end of the journal; Fig. 5 is on elevation of one of the rolls for the hub of Fig.

a designates the wheel-center, with chama and in its opposite ends to receive the casings Z and Z) of two roller-bearings. A journal 14 is shown. within the wheelccnter and provided'neor its opposite ends with hulis having roll-seets r; and 0-". Rolls '11 and 5 are shown fitted between the respective hubs and casings. A beveled firings e is formed near the outer end cit each huh with (in adjacent groove f, and 1 collar formed upon the roll and beveled to tit the :u ljocent face of the flange c.

The Henge 0 projects slightly beyond the Any frictional resistance these parts may and do not rub against the-bars of the cage (Z which guides them in their movement, as shown in Fig. 2. Any end-thrust upon the wheel-centertoward the flange c is transmitted to the roll. by a beveled flange or shoulder 0 upon the end of the casing Z) opposite to the flange c, and the endo'l the roll adjacent the flange c is provided with a ring it fitted loosely to a stud 2' upon the end of the roll.

The application of the wheel-center to the journal over the bearing-rolls, is facilitated by making the ring 71 smaller than the body of the roll, so that the casing b can be drawn over such ring in removing the wheel-center from the journal, which is effected in the usual manner by taking oil the cap and unscrewing the nut is from the journal.

The parts of the two bearings upon the opposite ends of the journal are similar but disposed reversely to one another, so that the ends of the rolls nearest one another are provided with the rings h and the ends remote from one another are provided with the collars g which bear directly upon the thrust-flanges on the hubs.

As the "beveled bearing-surface of the rings it is smaller than the body of the roll the ring rotates at a. velocity slightly different from the body of the roll, and any friction caused by its rubbing under pressure against the adjacent end of the roll (in resisting end-thrust) may be reduced by inserting an anti-friction washer Z between the ring and the roll-end, as shown in Fig. 1, or

by forming the same parts with ball-races and inserting balls m, as shown in the same fi 'ure.

The beveling of the outer corners upon both ends of the cylindrical rolls is employed to avoid the grinding effect which would be produced by a sharp corner upon the collar 9 or the ring h which is liable to occur in practice, and which is easily avoided by the form shown in the drawing.

From the above description it will be seen that the construction permits the cylindrical rolls to resist end-thrust with very little friction upon the bearing'parts and without any tendency to twist the roll from its required parallelism.

Having thus set forth the nature of the invention what is claimed herein is:

1. A roller-bearing having a series of cylindrical rolls, cylindrical seats fitted to their inner and outer sides, with annular flanges upon the opposite ends of the respective seats projected beyond the line of each seat, each roll having a collar upon one end bearing against one of the said flanges, and having a central stud upon the'opposite end,
